An international team of scientists have detected ripples in space and time, known as gravitational waves, from the biggest known black-hole collision that formed a new black hole about 80 times larger than the Sun – and from another three black-hole mergers.The Australian National University (ANU) is playing a lead

Smart home devices are getting momentum. According to reports, over 39 million people in the United States alone own a smart voice assistant, also called smart speaker.Smart Speakers are easy to use and come with a well known in-home voice assistant such as Siri, Alexa, Google Assistant, or Cortana. Home smart

Astronomers have measured all the starlight that has managed to escape into space over the history of the universe.It amounts to 4 x 1084 particles of light, or photons. That’s roughly equivalent to all the photons the sun would emit if it burned for 100 billion trillion years — long

Gathering detailed information on exoplanets is extremely difficult. The light from their host star overwhelms the light from the exoplanet, making it difficult for telescopes to see them.But now a team using cutting-edge technology at the Keck Observatory has taken a big leap in exoplanet observation and has detected water

Astronomers have spotted a mysterious "ghost" galaxy orbiting the Milky Way. Huge but extremely faint, the oddball galaxy has been named Antlia 2, and it might just be weird enough to force us to rethink what we know about galactic physics and dark matter.Ant 2, as it's also known, is

The origin story of Earth is a tale of God-like cosmic forces and geological timespans so colossal they are almost unimaginable to our puny brains. According to flat-Earthers, the results of this mysterious astronomical inception might look a lot like a fried doughy piece of confectionary.Abandon all scientific reasoning for

Black holes occur when a massive star dies and collapses with enough gravity that nothing, not even light, can escape from it. Black holes can absorb the surrounding mass and grow – eventually turning into supermassive black holes that can lie at the center of galaxies. Now a team of

It's hard to believe that we still use climate change-inducing fossil fuels when we have a sun that's bombarding our planet with plentiful, clean renewable energy on a daily basis. But fossil fuels do have one oft-overlooked advantage over solar power that has long prevented solar from truly emerging: they're

Interstellar mystery rock Oumuamua might have been part of an alien reconnaissance mission, according to two Harvard Smithsonian astronomers who saw in the strange object signs it could be a light-driven probe. As the strange rock moved out of our solar system last September, it sped up instead of slowing

After 11 years exploring the asteroid belt, NASA's Dawn mission has come to the end. On Monday, the space agency confirmed that all contact has been lost with the deep space probe after it failed to make two scheduled communications with the Deep Space Network (DSN) on October 31 and

Household lightbulbs give off a chaotic torrent of energy, as trillions of miniscule light particles—called photons—reflect and scatter in all directions. Quantum light sources, on the other hand, are like light guns that fire single photons one by one, each time they are triggered, enabling them to carry hack-proof digital

An international team of physicists reports that they have successfully produced a Bose-Einstein condensate in space for the first time. In the study published this past week in Nature, the group describes how they created a small device capable of producing a Bose-Einstein condensate, attached it to a rocket, and the
